Modes of Assessment

There are a total of 3 modes of assessment to ascertain your competency for the desired tier. These are: the Logbook, Assessment Test, and Case Study (only on Appeal). This section provides more information on each mode of assessment.


The logbook will be used to assess the applicant’s key tasks and responsibilities and project experience. The project write-up(s), peer reviews and supervisor’s assessment will also add further verification on the applicant’s critical core skills such as communication and digital literacy. The logbook should list the candidate’s work experience in BIM and IDD projects. There is a validity period of 5 years for projects handled or completed by the applicant to be considered towards accreditation. Each project should have the minimum GFA of not less than 5000sqm to be considered. The contact details of the candidate’s supervisor and HR Manager shall be listed in the document as the Assessment Committee for the DDM Accreditation Scheme may seek clarification from the supervisor or peers listed in the logbook to request further information or support documentation to verify the competencies of the applicant. The peer could be the applicant’s supervisor or project team members who had worked on the same project as the applicant and should be of equivalent or higher standing than the applicant (e.g. Project Director). The logbook must show that the candidate is able to meet 75% of Key Tasks stated in the Skills Map. For Lead accreditation, the candidate is required to produce a BIM or IDD Execution Plan that they have authored as part of the documentation submitted.

“Without qualification” refers to someone whose academic background is not from the Built Environment.

An administrator will call up the references listed in the logbook for verification. If our administrator finds that the candidate has submitted falsified information in the logbook, they will be failed and barred from taking the accreditation.

Assessment Test

The Assessment Test is a compulsory aspect of the Accreditation Framework. It verifies that the candidate meets the Technical Skills and Competencies as listed on the Skills Map.

Questions for the Assessment Test are not software or platform specific as the industry uses different tools for different purposes. The test will focus on the methodologies and applications, rather than skill set or competence in the use of a particular software or tool. The Question Bank is created and validated by a team of industry professionals and representatives from Institutes of Higher Learning. The questions will be primarily based on the Core TSC Modules identified as crucial for a DDM professional to function at the workplace. A short section of the assessment will be based on TSCs which the candidate may elect based on their background.

While the Assessment Test will be available on a twice-yearly basis, candidates can attempt the Skills Assessment once a year. Candidates who have failed the skills assessment can only retake the assessment in the following year. The Assessment Test will be held in-person at 159 Sin Ming Road #05-03 Amtech Building Lobby 1 Singapore 575625. In light of the current COVID-19 climate, the assessment test will be held with consideration to social distancing measures. The results will be published immediately. An invigilator will be assigned to run the Assessment Test to ensure no violation of test conditions. Candidates will be provided a document stating the tasks required to be performed according to our assessment plan and given a standard time to complete, unless he/she has disabilities that require to be considered. The assessment plan will be designed such that our assessor can verify immediately if the candidate has successfully completed the task and demonstrated desired skills. If the candidate is considered “Not Yet Competent”, the assessor will explain the reason for failure, and make recommendations on how to build the skills required. The assessment questions will be based on the Technical Skills and Competencies (TSCs) as listed in the Skills Map for each position. To pass the Skills Assessment, it is a requirement that the candidate must meet the passing mark requirement of all the Core modules as listed in Section 4.0 (Accreditation Criteria), as well as 50% of the other TSCs listed in the relevant Skill Map. The candidate will only be allowed to attempt the assessment test if they have been assessed to meet the qualification and logbook requirements. They will not be allowed to attempt the test first and apply for accreditation later.

Case Study

If the candidate is failed based on logbook submission and/or Assessment Test, they may mount an appeal if there are sufficient grounds to do so. The case study is to be presented to the Appeal Panel to make critical observations about the candidate’s ability to function in the accredited job role. The case study is submitted to the Appeal Panel which reviews failed applications. By providing additional insight into the candidate’s past work experience and skills, the panel will make a more fine-tuned judgment about the candidate’s ability to be certified.
